Description

[Detailed description of the invention] The present invention relates to a thigh support device for a vehicle seat. Specifically, the thigh support pad and the front part of the seat cushion pad are supported by a synthetic resin support plate of the thigh support pad. The present invention also relates to a thigh support device in which the support plate is supported by an elastic support member of an inclination angle adjustment mechanism.

Conventionally, thigh support devices that tilt the thigh support section provided at the front of the seat cushion are
A support plate that supports a thigh support part is swingably attached to the seat frame, and a tilt angle adjustment mechanism is provided in the middle of the support plate.

The fulcrum of the tilting of the support plate is set below the rear end of the thigh support part, and the thigh support part is tilted around the rear end.

On the other hand, a groove for suspending the skin is formed in the pad at the boundary between the thigh support part and the seat cushion body.

For this reason, when the thigh support part was tilted, a difference in level was felt at the boundary with the seat cushion body, which was uncomfortable.

Further, the support plate that supports the thigh support portion and the inclination angle adjustment mechanism are not flexible, which causes inconvenience in pedal operation and the like.

The present invention aims to eliminate such defects of the conventional device.

The basic structure of the present invention to achieve the above object is that the thigh support pad and the front part of the seat cushion pad are supported by a synthetic resin support plate of the thigh support pad, and the support plate is The thigh support part is tilted by being supported by the elastic support member of the tilt angle adjustment mechanism.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an exploded perspective view of the thigh support device of the present invention, in which 1 is an inclination angle adjustment mechanism and 2 is a support plate.

The tilt angle adjustment mechanism 1 includes a rotation shaft 3 and an elastic support member 4.
Consists of etc.

The rotation shaft 3 is rotatably mounted on the front part of the seat frame 5, and a mechanical brake 6 and a lever 7 are attached to one end, and the rotation of the lever 7 causes the rotation shaft 3 to rotate. However, as soon as the lever 7 is released, the rotation shaft 3 is fixed by the action of the mechanical brake 6.

The elastic support member 4 is made of a coil torsion spring or the like and is fixed to the rotating shaft 3, and a weak coil spring 8 for preventing the mechanical brake 6 from rattling is fixed to the tip thereof.

The support plate 2 is made of synthetic resin, and is provided with a hook 9 at the rear, a locking frame 10 at the lower front surface, a locking piece 11 at an appropriate position near the rear of the upper surface, and furthermore, at the front and rear of the locking piece 11. Several parallel stripes 12 are formed over the entire length.

Further, the support plate 2 is attached by hooking the hook 9 to a spring material 14 that can support the front part of the seat cushion pad 13, and by loosely fitting the elastic support member 4 into the hanging frame 10. Locking piece 1
The support surface on the front side of the seat supports the thigh support pad 15, and the front part of the seat cushion pad 13 is supported on the support surface on the rear side.

Further, the locking piece 11 is attached to the seat cushion pad 1.
3 and the thigh support pad 15, and the epidermis 17 is suspended with a clip (FIG. 2).

The tilting of the thigh support part 18 by the thigh support device of the present invention constructed as described above is performed as follows.

When the lever 7 is rotated clockwise in FIG. 1, the rotation shaft 3 rotates and the elastic support member 4 rotates to push up the support plate 2 and tilt the thigh support portion 18.

At this time, the support plate 2 rotates around the hook 9 that is hooked to the spring material 14, so as the thigh support part 18 tilts, the front part of the seat cushion pad 13 is also pushed up integrally. There is no difference in level between the seat cushion pad 13 and the thigh support pad 15 at the hanging part 19 of the skin 17.

Further, since the thigh support portion 18 is supported by the elastic support member 4 and the flexible support plate 2, it can be appropriately bent and pedal operations etc. can be performed easily.

Since the present invention is constructed as described above, it has the following effects.

Since the front parts of the thigh support pad and the seat cushion pad are supported by one flexible support plate, there is no difference in level at the boundary between the two, and no discomfort is caused to the thighs.

In addition, since the thigh support portion is appropriately bent, problems during pedal operation are eliminated, and fatigue during driving is reduced.
